그 정화장치는 고속으로 회전하는 브러시(여타의 필터포함)에, 바람직하게는 세정액의 분무와 함께 원심력을 발생시키면서 여기에 처리가스를 통과시켜 가스 및 이물질을 회전하는 필터의 여과작용에 의하여 분리되게하고 필터를 통과한 청정가스를 배출시키는 한편 필터에 여과된 이물질은 원심력에 의해 원주방향으로 배출시키는 구조를 특징으로 한다. 또, 세정액을 분무시켜 혼합시킴으로써 이물질을 보다 효율적으로 흡착, 여과시키면서, 필터를 세정하고 고속회전하는 필터의 회전안내부분에 유막을 형성시킬 수 있으며, 처리가스에 고압전위를 인가하여 이물질을 정전하로 대전시킴으로써 더욱 여과효율을 높일 수 있고 나아가, 처리가스의 용량이 가변적인 때에는 하나의 처리가스실과 청정가스실 및 그 사이의 필터를 하나의 분할된 섹션으로 구성함으로써 섹션수를 증감시킬 수 있다.The purifying device is provided with a brush (including other filters) rotating at a high speed, preferably with a spray of a cleaning liquid and a centrifugal force while generating a centrifugal force, passing a process gas therethrough and separating the gas and foreign matter by a filtration action of a rotating filter And the cleaned gas passing through the filter is discharged, while the foreign matter filtered on the filter is discharged in the circumferential direction by centrifugal force. In addition, by spraying and mixing the cleaning liquid, the filter can be cleaned while more efficiently adsorbing and filtering the foreign substance, and the oil film can be formed in the rotation guide portion of the filter rotating at a high speed. By applying a high voltage potential to the process gas, When the capacity of the process gas is variable, the number of sections can be increased or decreased by configuring one process gas chamber, the clean gas chamber, and a filter therebetween into one divided section when charging is performed.
